Working with Actions in Redux

The object below is a complete Redux action. Logging its two fields prints the event name and the data that goes with it:

const action = { type: 'todos/addTodo', payload: { id: 1, text: 'Learn Redux' } };
console.log(action.type, action.payload);

todos/addTodo { id: 1, text: 'Learn Redux' }

There is no class to extend and no function to register. An action is a plain JavaScript object that describes something that happened in the app. Components send actions to the store, and the store's reducer reads them to decide the next state
